Abstract
To improve mass production of fluorescent lamps, and introduction of merc within the interior thereof, the lamp mount includes an electrically conductive strip, band or wire secured within the vessel, to which a heater wire (11, 31, 40) is connected, the heater wire being melt-connected to extend into the glass capsule, forming therein a narrow V, or U-shaped structure. Upon application of a high frequency field, the heater wire will heat and open the glass capsule in the region of the melt-through connection thereof, thus liberating mercury previously introduced into the glass capsule, for example in the form of a drop, a pellet of porous substance with mercury dispersed therein, or the like.
